I decided to dust off the ol' HBK 2. Worked fine for a couple years and haven't gotten into it for maybe a year. It worked fine before, but now it's going nuts.

What I got is a hobbywing 25a esc and a xtreme 400x. it does the startup noises like it should, gyro initializes and looks good. as soon as i start with the throttle, the motor basically has a seizure and heats up. I have another 400x and it does the same thing so i'm thinking esc.

Fresh batteries all around.

Anyone with any input? What the hell?
